The ISDN

The Integrated Services Digital Network (ISDN) is a telecommunications network designed to transmit and process all types of voice and data traffic using digital transmission and switching. The ultimate goal of ISDN is to provide a common set of interface standards that will allow worldwide access for users.

There are two types of ISDN service: the Basic Rate Interface (BRI) and the Primary Rate Interface (PRI). BRI uses a standard 2-wire telephone line to provide two B (or bearer) channels supporting transmissions at 64 kbps and one D-channel at 16 kbps. Because of this, BRI is also commonly referred to as 2B+D. The B-channels can carry voice, circuit switched data, or packet switched data at rates up to 64 kbps; the D-channel carries signaling information or packet switched data at rates up to 16 kbps. BRI is typically used for a connection to a residence or small office.

PRI provides 23 B-channels and one D-channel, all supporting speeds up to 64 kbps. In PRI, the B-channels are again used for voice or data, and the D-channel is used for signaling or packet switched data. PRI is typically used for connections to an ISDN PABX in a large corporate office.

A typical configuration for an ISDN BRI connection is

shown in Figure 1. The various components in the network

are identified as network terminations and terminal equipment. The interface points are identified as R, S, T, and U. These components are explained in the tables following the illustration.

Definitions and Explanations

To better understand the operation of the auroraPlus_{, it}

helps to understand how different parts of the Basic Rate ISDN service are identified in operation. The first part of this section clarifies the difference between the central office switch that is providing the ISDN service and the D-channel protocol that the switch is using to control calls. The next part discusses some important differences among frequently confused ISDN terms: Terminal Endpoint Identifier (TEI), Service Profile Identifier (SPID), Directory Number (DN), and B-Channel.

Switch Type and Pr

ype and Pr

ype and Protocol

otocol

ISDN users and technicians often confuse the type of central office switch that is providing an ISDN service with the D-channel protocol that the switch is using to control calls. This confusion arises because, when ISDN first appeared, each of the major switch vendors offered its own variation on the standard D-channel protocol. Later, to reduce confusion and to make ISDN services more widely available, the North American telecommuni-cations industry adopted the National ISDN standard to replace the vendors’ custom protocols. Some of the

behavior of the ISDN circuit and the auroraPlus _depends

specifically on switch type and applies whether the switch is using the National ISDN protocol or a custom protocol. A circuit’s switch type is simply the make and model of the central office switch providing the ISDN service. In North America, the most frequently used brands of central office switches are the AT&T 5ESS and the Nortel DMS 100.

(15)

The protocol used on an ISDN circuit is the specific set of messages and procedures used on the D-channel to control calls. Three major variations of the D-channel protocol are used in North America: the National ISDN protocol, the AT&T Custom protocol, and the Nortel Custom protocol. The AT&T and Nortel Custom protocols run on AT&T and Nortel switches, respec-tively; the National ISDN protocol can run on any type of switch. The AT&T Custom protocol uses two different connection modes: point (PP) and point-to-multipoint (PMP).

Addresses and Identifiers in Basic Rate ISDN

Because it must support the wide range of services and features that ISDN offers, the Basic Rate Interface is fairly complex. First of all, the interface is divided into three channels. The two B-channels carry only the user’s voice or data calls. The D-channel carries

the signaling messages that control calls on the

B-channels; it can also carry low-speed packet switched (X.25) data communications.

Some additional complexity arises because the ISDN Basic Rate Interface is designed to support more than one device at a time. The S-interface, described earlier, is a bus that can connect up to eight different devices (telephones, fax machines, computers, data terminals, etc.) to the Basic Rate Interface (although only two of them can be active at once). The central office switch needs to be able to distinguish between the different devices so it can direct calls to specific devices. The switch also needs to be able to restrict the services it is offering to the set of services that the user has actually ordered.

vice Profiles and SPIDs

ofiles and SPIDs

The Service Profile of a BRI service is a record in a data base that the central office switch uses to determine how to serve a specific customer and how to handle specific commands and requests (such as feature keys) from a piece of Customer Premises Equipment. In most cases, when BRI services are provisioned, each terminal device on the service receives one or more Service Profile Identifiers (SPIDs) that identify the service profiles assigned to the service. (Circuits using the AT&T Custom protocol with point-to-point connection type do not use service profiles and, therefore, have no SPIDs.) The SPID usually includes the service’s directory number and some additional digits of information.

The ISDN user receives a written copy of the SPIDs for his BRI service from the service provider. The TE device must be programmed with SPIDs in order to initialize Layer 3, and subsequently place ISDN calls. Depending upon the software revision active in the switch and in the TE, the TE either requests SPIDs from the switch or submits pre-programmed SPIDs to the switch.

When the auroraPlus_{initializes, it sends a message to the}

switch requesting the SPIDs for the line. If the switch does not respond, the auroraPlus_{then tries to ‘guess’ the}

SPIDs for the line based on the values resident in non-volatile memory. The contents of SPID1 and SPID2 are assumed to be directory numbers, and are used with the National ISDN SPID Simplification rules to derive SPID numbers and submit them to the switch.

Some ISDN switches (such as the 5ESS) can connect multiple B-channel calls with only one SPID. Others, such as some versions of the Nortel DMS 100, require a separate SPID for each active call. Note that this feature depends on switch type and not on protocol.

(17)

TEI

The Terminal Endpoint Identifier (TEI) is a portion of the address that identifies a device on the D-channel for call control signaling. From the viewpoint of the signaling

protocol, a Terminal Endpoint can be an actual, physical

terminal, or it can be a logical entity associated with part of a basic rate service. Whenever a BRI service is initialized (i.e, turned up), the switch assigns one or more TEIs to the circuit. In North American ISDN, a TEI is uniquely associated with a service profile (i.e., one TEI is assigned per SPID). In some instances, a specific service requires that a specific fixed TEI be assigned. D-channel X.25 service on a Nortel switch is an example of this.

When a terminal device such as the auroraPlus_{begins to}

turn up the interface, it requests a TEI assignment and then transmits its SPID over the data link associated with that TEI for verification. (For a second Service Profile, it repeats the process and receives another TEI.) For terminals or services that use a fixed TEI, the terminal simply tells the switch which TEI will be used for messages for that service.

A BRI service can have one or more directory numbers. These are the ordinary telephone numbers used to dial that service from the outside. Customers and technicians often confuse the directory number with the SPID. The directory number is usually part of the SPID, but the SPID usually contains additional digits.

B-Channel

A B-channel on a BRI service is one of two 64 kbps digital channels available for voice or data calls. In most cases, specific B-channels are not associated with specific directory numbers or SPIDs. This allows the central office to assign an incoming or outgoing call for an ISDN service dynamically to the first available B-channel.

U-Interface Turn-up and Service Check

You can use the U-interface turn-up and service check described below to check newly installed circuits. This test shows that the circuit can be initialized and then deter-mines which services are available on your ISDN connec-tion for outgoing calls, letting you verify that you received the services you ordered. The test consists of four basic steps:

• Making the connection to the interface

• Selecting the protocol and connection mode

• Programming the required SPIDs

• Initiating the service check

To set up the test, you will need to know how your ISDN connection is provisioned, including the type of central office switch, the ISDN protocol (AT&T, National ISDN, or Northern Telecom), and the connection type (point-to-point or (point-to-point-to-multi(point-to-point) used on the circuit under test.

Use the following steps to initialize and test the line:

1 Make sure that the S/U switch on the keypad is in the

“down” (U) position.

2 Set the ISDN/Analog POTS switch to ISDN.

3 Connect the appropriately terminated U-interface

cord from the auroraPlus_{to the ISDN U-interface}

connector of the circuit under test.

In North America, the switch uses a SPID to identify which software features a piece of terminal equipment has

access to. Upon Layer 3 initialization, auroraPlus_attempts

to poll the switch for SPID numbers registered to that interface. If the switch does not respond (indicating that it

is not AutoSPID capable) the auroraPlus_{then tries to}

‘guess’ the SPID(s) for the line using the values in the SPID1 and SPID 2 registers as the basis for the calcula-tion.

To configure the SPID(s) manually: NOTE

SPIDS are used on a BRI service in point-to-multipoint mode. If you are using the AT&T protocol in point-to-point mode, a SPID is not required and will not be transmitted even if you enter one. In this case, you can skip to step 20.

Steps 11 through 19 explain how to program the SPIDs manually if you know them.

If you do not know the SPIDs, use this procedure to fill in the 10 digit DN(s) for the line in place of the

SPIDs. When connected, auroraPlus_{will attempt to use}

AutoSPID. If this fails, auroraPlus _{will use the DNs you}

have entered to automatically derive and submit the SPIDs. If this ‘guessing’ algorithm fails, you must enter the SPIDs manually.

When the signaling protocol becomes active and the switch has accepted the first SPID, the tester will display

SPID 1 OK (and possibly SPID 2 OK) and you see L3↑. This progression of messages layer through three stages of layer activation can provide important diagnostic information if the circuit fails to initialize. When the

initialization is complete, the IDLE message appears. This

sequence of messages is an important diagnostic aid in ensuring that the ISDN line initializes properly.

NOTE

While initializing the U-interface, the switch transmits a few control messages over the Embedded Operations

Channel (EOC). The auroraPlus _{displays these messages as}

they are received. You can access this information under the Status display.

If there is a problem:

• If you do not see L1↑ (layer 1 up) after about two

minutes, one of the following conditions applies:

• The S/U selector button on the auroraPlus_{is in}

the wrong position.

• The cable from the auroraPlus_{is not connected}

to the ISDN circuit.

• There is no ISDN service on the circuit.

• If you have set up the tester correctly, but it still does

not display L1↑ after approximately three minutes,

the physical layer of the circuit has failed and must be repaired before any further initialization or testing is possible.

• If the tester displays L1↑ but shows L2↓ after

approximately three minutes, the switch and the tester have failed to establish a data link; this indicates a probable hardware failure in the switch. If

the message L2 TEI err appears, this provides a

positive indication of a failure at layer 2.

• If the tester displays L2↑ but fails either to accept or

reject the first SPID within a few minutes, it displays

SPID1 timed out, check setup. This indicates a timeout for the SPID acceptance, which usually means failure in the switch.

• If the switch does not accept any of the SPIDs sent by auroraPlus_{the message}_{SPID1 Err}_{is displayed.}

Testing the S-Interface

The S-interface test verifies the ISDN line from the customer’s side of the NT1 between the NT1 and the Terminal Equipment (see Figure 2). The test is similar to the U-interface test described in the previous section. Like the U-interface test, the S-interface test also has different procedures for circuits with only one SPID and circuits with two SPIDs.

D-Channel Packet (X.25) Test

The test described in this section verifies the presence of a correctly operating D-channel packet service on your BRI circuit. The test consists of four basic steps:

• Making the connection to the interface

• Configuring for protocol, connection mode, and

SPIDs

• Configuring parameters for the X.25 line

• Initiating the X.25 call

To set up the test, you must know the following informa-tion about the X.25 line so that you can configure the parameters properly:

• The logical channel (LCN) on which the call is to

be sent

• Whether or not a Closed User Group (CUG) is

to be used

• Whether or not a specific Recognized Private

Operating Agency (RPOA) is to be used

• Whether or not the reverse charging facility is to be

used

If you are not familiar with these parameters, or do not know how to configure them for your X.25 line, contact your X.25 service provider.

If you have not set up the connection, interface, or SPIDs, start here:

1 • To set up the test to run on the U-interface,

follow steps 1 through 5 of the U-Interface Turn-up and Service Check earlier in this chapter.

• To set up the test to run on the S-interface, follow steps 1 through 5 of the procedure Testing the S-Interface earlier in this chapter.

(41)

2 If the correct protocol and connection mode have not yet been set up, follow steps 6 through 10 of the U-Interface Turn-up and Service Check earlier in this chapter.

3 If the correct SPIDs have not yet been entered and

you want to enter them manually, follow steps 11 through 21 of the U-Interface Turn-up and Service Check earlier in this chapter.

4 If the circuit has not been initialized, follow step 22 of

the U-Interface turn-up or step 7 of the S-Interface test procedure.

If the preliminary configuration has been done (connection, interface, and SPIDs) and the circuit initialized, start here:

Dual B-Channel Data Call Test

The 2B Check verifies that the service under test can accept two simultaneous, outbound B-channel data calls; this provisioning option allows an ISDN user with the correct terminal equipment to make a 128 kbps “bonded” data call. This test is designed to run on data channels only; it will fail if one or both of your

B-channels are configured only for voice. If you need to determine how your B-channels are configured, refer to the U-Interface Turn-up and Service Check procedure earlier in this chapter.

If the BRI circuit that you are testing uses either the National ISDN or Nortel Custom protocol, you might need to enter two valid SPIDs at initialization time to perform the 2B Check correctly. If the BRI circuit uses the AT&T Custom protocol in point-to-multipoint mode, then at least one SPID is required. (With the point-to-point connection type for the AT&T Custom protocol, no SPIDS are required.)

If you have not set up the connection, protocol, or SPIDs, or you have not yet initialized the circuit, start here:

1 To set up the test on the U-interface, follow steps 1

through 5 of the U-Interface Turn-up and Service Check earlier in this chapter.

Testing for Bit Errors

Once you have verified the SPID(s) on the BRI circuit, you can perform a BERT (Bit Error Rate) self-call for any ISDN service (speech or data) to check the quality of your ISDN line. You set up a call either to the second B-channel

on your auroraPlus_{or to a remote test device for a length}

of time of your choosing (30 seconds, 1 minute, 5 minutes, 15 minutes, continuously, or a user-defined duration). The data received during the test is checked for errors, and the number of errors and the corresponding error rate are displayed once the test is completed. See Setting Up a Loop in Chapter 5 if you want to loop incoming calls for BERT testing with another device. You can run a BERT test during any outgoing call. However, the test will use the parameters (BERT dura-tion) that have been set up previously.

If you have not set up the connection, protocol, or SPIDs, or have not initialized the interface, start here:

1 To set up the test on the U-interface, follow steps 1

through 5 of the U-Interface Turn-up and Service Check earlier in this chapter.

Placing and Receiving Calls

Introduction

This chapter explains in detail how to place and receive calls, including how to select the B-channel and the service type. It also tells you how to use the speed dial and call waiting features. All procedures in this section assume that the tester has been initialized on the interface under test and is in the IDLE state. If this is not the case, see the sections U-Interface Turn-up and Service Check or Testing the S-Interface in Chapter 3.

Receiving a Call

Incoming calls using any service type are accepted. An incoming call is indicated by a ring tone, and the sub-scriber number of the calling party is displayed if it was transmitted. If a calling party subaddress is also available, it is appended to the subscriber number after an asterisk (*).

To accept the call:

Additional Functions

This chapter explains additional tests and capabilities of the auroraPlus_{. These include performing a self-test,}

displaying block errors, viewing the most recent results, setting up a loop, and reprogramming the tester. It also explains how to adjust the loudspeaker volume.

Self-Test

The auroraPlus_{self-test tests various functions of the}

device. These tests include a test of the display and an EPROM checksum test. A complete list of tests, with test codes and possible results, is given on pages 5-3 and 5-4. It is recommended that you perform the self-test off-line or on the S-interface with the auroraPlus_{in the idle state.}

Calls will not be indicated during the self-test. The auroraPlus_{resets itself after the self-test is successfully}

completed.

1 If you are performing the self-test on the S-interface

and you have not connected to and initialized the S-interface, follow the procedure Testing the S-Interface in Chapter 3.
